Applications of Steel Light Rail Q235B, 55Q, Q345B, 50Mn, U71Mn, 900A, 1100, R260

Light rail is mainly used in forest region, mines, factories and construction sites laid of the place such as temporary transport line and light motorcycles with line.

Heavy rail is suitable for the laying of main trunk line of the curves and the orbit of the tunnel can also be used for tower crane and other crane track.    

 

Packaging & Delivery of Steel Light Rail Q235B, 55Q, Q345B, 50Mn, U71Mn, 900A, 1100, R260

1. Packing: it is nude packed in bundles by steel wire rod

2. Bundle weight: not more than 3.5MT for bulk vessel; less than 3 MT for container load

3. Marks:

Color marking: There will be color marking on both end of the bundle for the cargo delivered by bulk vessel. That makes it easily to distinguish at the destination port.

Tag mark: there will be tag mark tied up on the bundles. The information usually including supplier logo and name, product name, made in China, shipping marks and other information request by the customer.

If loading by container the marking is not needed, but we will prepare it as customer request.

4. Transportation: the goods are delivered by truck from mill to loading port, the maximum quantity can be loaded is around 40MTs by each truck. If the order quantity cannot reach the full truck loaded, the transportation cost per ton will be little higher than full load. 

5. Delivered by container or bulk vessel

6. Delivery Time: All the Hot Rolled Steel Rail will be transpoted at the port of Tianjin, China within 30 days after receiving the advance payment by T/T or the orginal L/C at sight.

 

7. Payment terms:30% advance payment by T/T, 70% payment against the copy of the B/L; 100% L/C at sight, etc.

8. Others: Invoicing on theoretical weight or actual weight as customer request

Inspection of Steel Light Rail Q235B, 55Q, Q345B, 50Mn, U71Mn, 900A, 1100, R260

We will send the MTC of the factory to the clients directly which contains the anlisis of the heat, chemiqual composition, phisical characteristicas, etc.

And our inspectors will arrive at the factory to meke the inspection of the size, length, weight and quantity before the transportation from the factory.

Q:Why does the train not skid on the rails?
But in the actual operation, locomotive could slip, which is mainly due to the change of external conditions, the formula is in good condition to face, if there is oil, cream, water and other impurities on the track, or line quality is not good, may also be part of the locomotive itself result, the adhesion coefficient will decrease, when the locomotive traction motor traction play may be greater than the adhesive force, formed the so-called idle, the locomotive is harmful and must be eliminated quickly. Generally use sand to increase adhesion coefficient, no, then the locomotive will reduce load, reduce traction.
Q:Why can't the vertical rail bend the rail?
In order to solve this problem, the railway department within a certain distance, playing a few holes in the rail waist to release the energy generated by thermal expansion and contraction, and within a certain distance (about 1500m) retaining rail joint, to assist in releasing the energy generated by the thermal expansion and contraction, in order to solve the problem of rail expansion and contraction.
Q:How are the rail tracks worn?
Rail is the main component of railway track. Its function is to guide the wheel of the rolling stock, to bear the great pressure of the wheel and to deliver it to the sleeper. The rail must provide a continuous, smooth, and least resistant rolling surface for the wheel. In electrified railway or automatic block section, rail can also be used as track circuit.
Q:Why should there be a gap between the rails?
Avoid the rail due to "expansion, contraction" and the track extrusion deformation (cold winter, the track will shrink because of the gap between the larger; hot summer rail due to heat and gap smaller).
Q:What is a rail pile?
The rail is used as the material of the pile foundation to directly push the rail vertically into the ground to the design depth. The superstructure is supported by the friction force between the rail and the surrounding soil and the bearing capacity of the rail top and the bearing soil. Generally used for better soil conditions, buildings are not very large
Q:What are the reasons for the development of rail nuclear injury?
Because of the rapid increase of railway speed, heavy load and annual volume, rail damage is aggravated, especially in the songThe rail line, the line in a very short time because of head injury may produce a nuclear line.
Q:What is a rail flaw detector used to detect?
JGT-2 type rail flaw detector is usually used for flaw detection. The horizontal probe is mainly detected by a straight probe, and the smaller inclined crack can also be found. In the detection, the probe is placed on the rail surface and the defect is judged by the presence or absence of the bottom wave of the rail. When no bottom wave is indicated, the flaw detector sends out an alarm signal. There are no defects in rail, bottom wave. When there is a horizontal defect, there is a defect wave, no bottom wave. When there is an inclined crack, the defect wave decreases or disappears, and there is no bottom wave. If there is a horizontal or inclined crack near the screw hole, there is a screw hole reflection and defect wave, but there is no bottom wave. The part of the nuclear damage available 50 degree oblique probe, available before and after the screw edge inclined crack and waist 35 degree oblique probe, the rail weld with double 35 degree oblique probe.
Q:How to deal with old rail rail?
Two methods:1, the rails will be melted recast.2. Make rail into other landmark buildings.Note: old rail should be prepared after the public security reported.
Q:60 detailed dimensions of rail
The standard length of China's rail is 12.5m and 25.0m two kinds. Severe, heavy rail using standard length rail 25.0m, other types of track can be used 12.5m25.0m standard length rail.
Q:Structural classification of rails
The type of rail is expressed by the mass kilogram of rail length per meter. The rails used in China's railways are 75kg/m, 60kg/m, 50kg/m, 43kg/m and 38kg/m.
